Hydraulic Motor

I have a machine that uses hydraulic motors and I don't have the electrical diags. The function of the machine is pretty simple but I don't know how to program the seccion of the motors. They are reversible and use four solenoids, acording to the info the flor production people they have two speeds too. I am a little confused about this. Can anyone tell me how it works?
I apreciate any help.
Thanks in advance.
 
Hi

I think it,s working this way:
2 solenoids for left/right and the high speed.
2 solenoids for left/right speed with flow control so the speed can be reduced(ie 2 or 3 way flow-controlvalve or proportional valve)
A schematic or plc program to control this will be easy.

Four solenoids:
1. First sol.: Hyd. Motor forward (must be interlock with reverse solenoid)
2. Second sol.: Hyd. Motor reverse (must be interlock with forward solenoid)
3. Third + fourth sol.'s: High speed
4.Could use either third or fourth sol. for low speed

PROGRAM PLC OR WIRE AS BELOW SEQUENCE:

MOTOR FORDWARD: 1 ON + 2 OFF
MOTOR REVERSE: 2 ON + 1 OFF
HI SPEED FORWARD: 1 ON + 2 OFF + 3 ON + 4 ON
LO SPEED FORWARD: 1 ON + 2 OFF + 3 ON + 4 OFF

HI SPEED REVERSE: 2 ON + 1 OFF + 3 ON + 4 ON
LO SPEED REVERSE: 2 ON + 1 OFF + 3 ON + 4 OFF

Hope this information will be useful to you

Good luck,
